As if diesel isn't expensive enough yet, I still wanted to have a go with the relatively new Vpower diesel (nothing is too good for my baby)

I did not notice any significant increase in power (didn't expect too), neither was it getting more kilometers out of a liter. BUT the noise of the engine was a lot smoother.

The 535d has a "rough" spot between 1300-1600rpm, with this new diesel it was still there but much less pronounced.

Any other people having experimented with the new diesels?
I noticed HansNL does/did a testdrive for BP.

E60525d

I did notice a slight improvement with BP. It looks like that you have noticed a bigger difference. I will be trying Shell.

Not noticed any difference with BP Ultimate to be honest!

With Petrol I have tried Shell V, BP, Chevron, etc. etc. and I have not noticed any change, nothing at all...

My wife noticed it, as a passenger (doesn't like steptronic so she's always a passenger)

So it does something.

On the other side, somehow i think my cars behaviour changed after some 10000-11000
kilometres. I'm talking faster, more economic and quieter.
